An air compressor used with a paint sprayer does 64.0 J of work pumping air into a tank. Warmed by the process, the air in the tank gives off 37.0 J of energy to its surroundings. What is the change in the internal energy of the air in the tank as a result of the two processes?

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
